Answer:

Explanation:

Antimicrobials are probably one of the most successful forms of chemotherapy in the history of medicine. It is not necessary to reiterate here how many lives they have saved and how significantly they have contributed to the control of infectious diseases that were the leading causes of human morbidity and mortality for most of human existence. Contrary to the common belief that the exposure to antibiotics is confined to the modern “antibiotic era,” research has revealed that this is not the case. The traces of tetracycline, for example, have been found in human skeletal remains from ancient Sudanese Nubia dating back to 350–550 CE (Bassett et al., 1980; Nelson et al., 2010). The distribution of tetracycline in bones is only explicable after exposure to tetracycline-containing materials in the diet of these ancient people. Another example of ancient antibiotic exposure is from a histological study of samples taken from the femoral midshafts of the late Roman period skeletons from the Dakhleh Oasis, Egypt (Cook et al., 1989). These samples showed discrete fluorochrome labeling consistent with the presence of tetracycline in the diet at that time (Cook et al., 1989). The postulated intake of tetracycline in these populations possibly had a protective effect because the rate of infectious diseases documented in the Sudanese Nubian population was low, and no traces of bone infection were detected in the samples from the Dakhleh Oasis (Armelagos, 1969; Cook et al., 1989).

Why is the price elasticity of demand for Starbucks greater than the price elasticity for coffee generally? Explain your answer
lara [203]

Answer:

The price elasticity of a product shows how many percent the requested quantity changes as the price increases by one percent. In the normal case, the elasticity is a negative number, as demand decreases as the price increases; the reverse is extremely unusual.

In the case of large companies, however, the price elasticity of demand is usually much larger. This is so because not only characteristics such as the quality of the product are weighted, but also the brand itself has a value in itself, which sustains the variations in price. Thus, trendy brands such as Starbucks have an established clientele that will not vary due to small price variations. On the other hand, these companies offer a high variety of products, which liquefy said possibility of falling demand, granting greater elasticity.

if f(x)=x^2-x and g(x)=1/x and h(x) is defined with the expressions below, arrange the values of h'(1) from smallest to largest.
SSSSS [86.1K]
F(x) = x²-x

g(x) =1/x

1) h(x) =f(x) -g(x) = (x²-x) - (1/x) = (x³-x²)/x (x≠0) =>
2)h(x) =f(x).g(x) =  (x²-x).(1/x) =x(x²-1)
3)h(x) = f(g(x)) = (1/x)²-(1/x)

1What happens to the curve when the standard deviation is increased? What does that do to the area under the curve?
Umnica [9.8K]

Answer:

The answer is below

Explanation:

Z score is a score used in mathematics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

z=\frac{x-\mu}{\sigma}\\\\where\ x=raw\ score, \mu=mean,\sigma=standard\ deviation. \\\\For\ a\ sample\ size(n):\\\\  z=\frac{x-\mu}{\sigma/\sqrt{n} }

The area under the curve is dependent on the z score. The higher the z score, the higher the area under curve and the lower the z score, the lower the area under curve.

a) The area under curve (z score) is inversely proportional to the standard deviation. If the standard deviation is increased, the z score decreases thereby reducing the area under the curve.

b) If the standard deviation is decreased, the z score increases thereby increasing the area under the curve.
